With the rapid development of my country's infrastructure construction, especially the large-scale construction of high-speed rail projects in recent years, the quality requirements for commercial concrete during the construction process have become more and more stringent, and it is basically required that all high-performance concrete be used. In high-performance concrete, adding traditional polycondensation type water reducers like naphthalene, sulfamate, and melamine, the water reduction rate is average, and the production process of naphthalene and other water reducing agents will pollute the environment . Therefore, the environmentally friendly polycarboxylic acid water-reducing agent is widely used, and the amount of application is increasing year by year.
Nowadays, in pursuit of high water reduction rate, many polycarboxylic acid water-reducing agents have shortcomings such as easy bleeding, hardening, and poor workability in practical applications, and it is difficult to solve them through compounding methods. Compared with developed countries such as Japan, Europe and the United States, the research of water agents started relatively late. Many technologies are not very mature, and the quality of raw materials is not stable. In addition, there are many cement plants in my country with production technology, cement varieties, compositions, and fine details. The degree and the source of the mixed materials vary greatly. At present, most of the domestic polycarboxylic acid water reducers have defects such as poor compatibility with cement, weak adaptability to the environment, and rapid slump loss, which bring great difficulties to construction.
The raw material China 3-Mercaptopropionic Acid CAS 107-96-0 provided by our company is a concrete polycarboxylic acid with stable performance, high water reduction rate, and strong cement adaptability with excellent water reduction and slump retention properties. The 3-Mercaptopropionic Acid factory mentioned that its preparation process is simple, short in time, low energy consumption, strong operability and no pollution to the environment.
